I have a 1998 Buell S1 lightning, pops at low rpm, sometimes shuts off when put it in gear when restarting back fires then idles fine after a few try's it works, sometimes acts like its outta gas dies then don't want to start few try later everything's fine, hard to get in neutral engine running or off, sometime it hesitates when getting on it then runs great, all of these problem happen cold or hot! Right now it wont start at all wont turn over N light is not coming on but bike is in neutral.. any ideas what it could be an how to fix it? | ||

Sounds like your side stand interlock switch if flaky. Some folks bypass it in order to avoid ignition cutouts. | ||

First check the grounds,as well as condition of the battery, then the ignition switch as they are known to fail on tubers, and look at the neutral safety switch as well. If it goes you need the clutch in to start as bike thinks its in gear. | ||

If it is hard to get into neutral, your primary chain may need to be adjusted. Are you the original owner? | ||

how would you bypass the kick stand switch? Ill have to check the ground but the battery is new an how would i check the ignition an neutral switches? And I do have the clutch in when i start it but the light under the tack isnt coming on but the bike is in neutral just wont turn over at all the rest of the lights come on tho. | ||

no i just got the bike but i just had the primary cover off due the the time chain front sprocket nut coming off will deff check the timing chain i adjusted it how the service Manuel said it it might have tightened up some.. | ||

If you did not adjust the primary chain to 3/4 in. on the tight spot it will be too tight if you ride your bike like you stole it !!! PRIMARY CHAIN ADJUSTMENT Class 101, just PM me if you want a copy ... | ||

I believe that you can bypass the kick stand switch by just removing the connector from the switch which is attached to the kick stand. Then bend a piece of conductive wire (paper clip) in a U-shape. Insert the U-shaped wire so that each end of the U goes into one hole on the two pin connector you just removed. This is the same as cutting the connector off and twisting the two wires together. When done make sure to zip tie the connector securely out of the way. If you adjusted the primary chain per the Service Manual than it is too tight. The manual is wrong. You can find plenty of info here about that but if I remember right it should be 3/4" at the tight-spot. When you say "just wont turn over at all" do you mean the starter wont spin the engine? If that is the case it may be the ignition switch as already mentioned but could also be a bad starter relay. First buy a can of electrical contact cleaner spray (this will be handy to have around later anyway) and spray into the ignition switch then work the key on/off multiple times to ensure that the internal contacts are clean. Spray into switch gear switches (starter button). Now try again. I think that people will remove the ignition switch to be able to view the back-side to look for signs of burnt wires/contact on the back of the switch. You should have two relays plugged into a block together. My experience is all from and M2 so sorry if I'm wrong about the two relays. I believe you have them, just not sure where. Mine are on the right side of the frame under the seat fairing. One is a starter relay the other is an ignition relay. Remove them and spray with contact cleaner and reinsert them. Try again. If still fails switch the two, they are the same relay and if one goes bad you might be able to figure it out by switching them. I've never messed with the neutral sensor but I think I've read here that you can remove it and wipe it off and re-install and that sometimes does the trick. Not sure how involved or accessible it is though. | ||

not to sure what PM means today is my first day using i have always look at this site trying to find ppl with the same problems but yea if you have a copy that would be great im at school right now an i left my service Manuel at home.. thought i had the bike fixed it ran good all weekend made the two hour drive np started acting up again thing morning on the way to class.. after class it wouldnt start or turn over.. | ||

PM is personal message, go to posters profile by clicking on their name. At the bottom left is a link to email. The primary chain is the chain from the motor to the transmission. The primary chain is on the inside, the shifter side of the bike. | ||

Ignition switch connector is so easy to pull apart and just bypass with some wire,right under left side of fuel tank, big 3 wire connector pulls apart.Notorious for this. | ||

Bike is starting now but still shuts off when you put it in gear. | ||

Sounds like something in the Neutral light switch / sidestand switch circuit. It sounds like it thinks your sidestand is down. Jumper the connector at the sidestand for now, and I bet that fixes it. |
